Questions

How big is the Dom45 PCB?

It measures 179.9 × 103.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Dom45 use?

97 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Dom45 KiCad files?

From the dspez/macropad repository on GitHub, at the commit this page was made from: the board is dom45/dom45.kicad_pcb and its schematic dom45/dom45.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Dom45 design in my own project?

Its repository states no licence, so its author keeps all rights: ask dspez before reusing the design.
